2. Wobble Dubstep Grime Generator

You can make your own customized dubstep with this program, which promises to “make the most crazy, pulsating, and different sounds ever to grace your speaker’s soon to be aching cones.” If you get this on Christmas Day, you might pick it up fast enough to drop the bass on New Year’s Eve.

13. “Song Reader” by Beck

Beck’s new album is actually a book of sheet music. The 20 songs in this book have never been recorded, so it’s up to other musicians to determine how they should sound. You can buy it for $34 from McSweeney’s.

18. “How Music Works” by David Byrne

David Byrne’s new book is a collection of essays in which he reflects on the history of music, recorded sound, musicians’ relationship with their audience, and the economics of the music industry. It sounds very dry, but Byrne’s wry sense of humor and oddball perspective makes it all very lively. You can buy it for $28 from McSweeney’s.
